Configuring the RSVP refresh mechanism
To enhance reliability of RSVP message transmission, the Message_ID extension mechanism is used to
acknowledge RSVP messages. The Message_ID extension mechanism is also referred to as the reliability
mechanism throughout this document.
After you enable RSVP message acknowledgement on an interface, you can enable retransmission.
To use summary refresh (Srefresh), you must use the Message_ID extension. Only states advertised using
MESSAGE_ID included Path and Resv messages can be refreshed using summary refreshes.
